Js Beautify
js-beautify is a web language beautifier and code formatter designed to standardize the layout and structure of JavaScript, HTML, and CSS files. It reorganizes source code into a consistent, readable style by applying configurable indentation and spacing rules.
The project includes a utility for unpacking minified scripts, which transforms compressed or obfuscated JavaScript into a human-readable format. It provides a command-line interface for executing bulk code reformatting across multiple files.
The tool supports customizable formatting rules and language-specific overrides, which can be managed via configuration files, environment variables, or in-file formatting directives used to ignore specific code blocks.
Features
